BEATER IMEECHANIfiB/I FOE BBAIDING MACHINES.

Application filed January 12, 1923.

T (iii 107L071?! it may concern:

Be it known that I, IIERMAN STAUD, a citi' zen of the United States, residing at Wyemissing, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Beater Mechanism for Braiding Machines, of which the followin, is a specification.

lily ini ention relates to beater mechanism for braiding machines, and consists in an improved pivotal mounting of the blades and their operating links,to facilitate convenient assembling and ready replacement, as fully herein described in connection with the accompanying drawings, the novel features being pointed out in the appended claims.

Fig. 1 shows in vertical section part ot the head of a well known crown beater mechanism, indicating the beater blades and the connected operating links therefor, and embodying my improved pivotal mountings thereof.

Fig. 2 is a partial plan view of the same, with the beater blades and pivot retaining covers removed.

Fig. 8 is an enlarged cross-sectional detail showing a link secured by my improved pivotal pin.

The beater mechanism indicated in the drawings is well known, and the operation of its beater blades 10 and 10*, guided in radial slots of the usual central crown, not shown, is as heretofore and requires no "further description. The beater blades 10 and 10 are of ordinary form and are usually arranged in an alternating circular series with acommon pivotal bearing in the slotted fulcrum ring 12 on central shaft- 13. The beater blades of each series are jointly swung on their pivots, as heretofore, by camactuated vertically slidable sleeves 16 and 20, carried by shaft 13; the series of blades 10 being connected by links 17 to pivot ring flange 18 of sleeve 16, and the series of blades 1O being connected by links 21 to pivot ring flange 22 of sleeve 20.

The pivotal connection of the blades 10 and 10 in slotted pivot ring 12, and of the links 17 and 21 in the pivot rings 18 and 22 of sleeves 16 and respectively, has heretofore been provided for by single lengths of wire circularly bent to fill said ring grooves, one wire for the fulcrum ring and one wire each for the sleeve flange rings, upon which the blades and their links are strung prepar- Serial No. 612,187.

atory to entering them into their respective slots. These wires, because of the constant and rapid movement of the beater elements are hardened, to better withstand the wear, and in the hardening process are commonly distorted more or less, causing considerable waste, and require expert manipulation in assembling the parts; and moreover on the break of the heater or an actuating link, re quires disturbing one or more of said wires with its entire series of strung blades or links to replace the broken part witha new one. The object of my present invention is to do away with these hardened wire pivot rings and substitute therefor special individual pivot pins for each beater blade and for each link, so as to both facilitate assembling and replacement, as will now be described.

Each pivot pin, as shown, is formed of a straight piece of steel, readily hardened without distortion, and provided with an intermediate aperture engaging portion forming a pivotal bearing for its beater element, and each is provided with opposite reduced extensions adapted to abut against adjacent pins to loosely fill the circular groove in which they seat.

The pins 25 for the beater blades 10 and 10 because of the close arrangement of the slots 28 in the fulcrum ring 12, merely have spherical extensions 2727 on opposite sides of the aperture engaging portions 26, which latter is wider than said slot aperture 28 and its diameter slightly greater than the depth of the retaining groove 29, so that when the slotted clamping head 14 is firmly seated by nut 13 the latter will bear on'said portions 26 to fixedly space the pins in said groove in proper engagement with their respective beater blades. It will be understood that it the head 14- only engages one pin 25 it will fixedly position the entire series within the groove 29, due to the abutment of the extensions 27-27.

The pins 80 in pivot ring 18 of sleeve 16, are considerably longer than pins 25, due to the greater diameter of its circular groove 33 and the increased angular spacing of the slots 34 therein, the number of the latter being but half the number in ring 12 to correspond with the number of blades 10. This required greater length is provided in the increased length of reduced extensions on opposite sides of link aperture engaging portion 31, the latter being wider than slot 3% and of greater diameter than groove 33 so as to be fixedly positioned in a manner similar to pins 25, by seated clamping head 19.

These pins 30 loosely fill groove with their ends abutting, so that fixedly positioning one pin will position all, and the reduced extensions 32 are preferably just su'liiciently tapered, as shown, to conform with the outer Wall-curvature of circular groove 33, so that straight pins can be used, and such wall contact will radially position portion 81 for accurate swinging of link 17 thereon.

The pins 40 in pivot ring 22 of sleeve 20,

are shaped similarly to pins 30, but are of: a

size intermediate the latter and pins 25, so that their extensions 42 l-2 will abut in the groove a3 and radially position their link aperture portions 41 across the slots n, and they are held and positioned by clamping plate 23 in the same manner as pins 25 and 30.

With my improved invention each pivotal member oi the beater mechanism has a separate pivot pin connecting it to its pivot ring support permitting the use. of hardened strai ht pins, and providing for assembly of the parts and ready removal and replacement of any one when required without disturbing a Whole series; and the abutting pins loosely filling their respective circular grooves and projecting above the same, are readily linedly positioned by the clamping heads wien thus assembled; and moreover the separate pins can be cheaply formed from straight stock and hardened as desired Without loss due to distortion.

What I claim is:

1. In a beater mechanism for braiding machines comprising an axial support and raidially swinging beater elements having pivoting apertures; a pivot ring on said support having a circular pivot-pin groove and a series of intersecting radial slots, and a circular series of separately formed pivot pivoting apertures; a pivot ring on said sup port having a circular pivot-pin groove and a series of intersecting radial slots, a circular series of separately formed pivot pins engaged in said apertures and loosely filling said groove, and a groove closure adapted to fixedly position said pins in the groove.

3. In a heater mechanism for braiding machines comprising an axial support and radially swinging beater blades and actuating links therefor all provided with pivoting apertures; a fixed fulcrum ring for said heater blades, and an axially movable pivot ring for said actuating links, said rings having circularpivot-pin grooves of different diameters and corresponding series of open radial slots intersecting the respective grooves, a series of abutting pivot pins loosely filling the respective grooves and each engaged in a pivot aperture, the pins in the movable ring being of proportionately greater length than the pins in the fulcrum ring, and groove closures adapted to fixedly position said pins in their respective grooves.

a. In a beater mechanism for braiding machines comprising an axial support and radially swinging beater elements having pivoting apertures; a pivot ring on said support having a circular pivot-pin groove and a series of intersecting radial slots, and a circular series of separately formed pivot pins engaged in said apertures and fixedly spaced in said groove; said pins having an intermediate aperture engaging portion and opposite reduced extension adapted to loosely abut against adjacent pins and engage the wall of the circular groove to radially position said aperture engaging portion.

In testimony whereof I aflix my signature.
